In Time

In 2169, people are genetically engineered to stop aging on their 25th birthday, when a one-year countdown on their forearm begins. When it reaches zero, the person "times out" and dies instantly. Time has thus become the universal currency, transferred directly between people or stored in "time capsules". Several major areas called Time Zones exist; Dayton is the poorest, a manufacturing "ghetto" where people rarely have over 24 hours on their clocks, whereas in New Greenwich, people have enough time to be essentially immortal.
